Introduction
PDWR wireless signal repeaters are used to improve
the connectivity in PDW30 point to point and PDW90
point to multi-point wireless systems. They will
generally increase signal range of the system by
another 1 mile line-of-sight or 500 feet indoor.
The repeaters are simple to install as they only
require power and a network ID. Any PDW wireless
units in range of the repeater with the same network
ID will retransmit through it, thus increasing signal
strength.
PDWR repeaters can be used to broadcast over very
long distances or around permanent obstacles.
The PDWR repeaters are available in either aluminum
or stainless steel NEMA 4X, IP68 enclosures and
these enclosures contain plenty of room for field
wiring connections.

CapTouch Through-Glass
Buttons
The PDWR repeater units are equipped with four
capacitive sensors that operate as through-glass
buttons so that they can be operated without
removing the cover (and exposing the electronics)
in an unclean area.
CapTouch buttons allow the Network ID to be programmed without removing the cover.
CapTouch buttons are designed to work under any
lighting condition and are not affected by random
changes in light or shadows. To protect against false
triggering a long button press of about 2 seconds is
required to wake up the buttons when they have not
been in use.
Repeater Units Available in
Aluminum or Stainless Steel
The PDWR repeater units are available in an IP68,
NEMA 4X aluminum or stainless steel enclosure. The
enclosures feature a built-in flange for wall or pipe
mounting, built-in loop for a stainless steel tag, locking
screw, and hole for a tamper-proof wire & seal. The
enclosure also includes two 3/4" threaded conduit
openings for wiring. The PDWR repeater units can
operate in temperatures of -55 to 75°C (-67 to 167°F).

CapTouch Buttons
The PDWR repeater is equipped with four capacitive
sensors that operate as through-window buttons.
Their only function is to change the network ID; which
due to through-window buttons, can be changed without removing the cover (and exposing the electronics)
in a harsh operating area.
The first time the CapTouch buttons are used, or after
20 seconds of inactivity, a long finger press for about
two seconds directly over the marked button area of
any button is required to wake up the buttons. After
that, a brief press directly over the marked button
area is all that is required to actuate a button.
When the cover is removed or re-installed, the
CapTouch buttons can be used only after the meter
completes a self-calibrating routine (which can take
up to 20 seconds). Additionally, the sensors are disabled when more than one button is pressed, and they
will automatically re-enable after a few seconds.
CapTouch Button Tips
The CapTouch buttons are designed to work under
any lighting condition and to protect against false triggering.
• Keep the window clean.
• Tighten the cover securely.
• Use a password to prevent tampering.
• The first time the CapTouch buttons are used, or
after 20 seconds of inactivity, a long finger press
directly over the marked button area of any
button of about two seconds is required to wake
up the buttons.
• When the cover is removed or re-installed, the
CapTouch buttons can be used only after the
meter completes a self-calibrating routine (which
can take up to 20 seconds).
• CapTouch buttons will not work if two or more
buttons are detected as being pressed
simultaneously. Be careful to avoid triggering
multiple buttons or reaching across one button
location to press another.
PDW Manager Software
The units can also be programmed using the PC
based PDW Manager. Units connect to a PC via the
micro USB connection on the left side of the display
module, underneath the enclosure cover.
Use of PDW Manager is required for programming
advanced settings, such as wireless encryption.
• Units must be powered externally prior to
programming via USB.
PDW Manager is available for download at
www.predig.com/pdwmanager.
